10-7-3 Outlet test - wiring arrangement
Test all outlets in the area for proper grounding and wiring
arrangement by plugging in the neon outlet tester and noting the
combination of lights that are illuminated. Any problems found
should be reported to the hospital immediately and the
receptacle should not be used.
Figure 10-1. Typical alternate outlet tester
NOTE: No outlet tester can detect the condition where the Neutral
(grounded supply) conductor and the Grounding (protective
earth) conductor are reversed. If later tests indicate high leakage
currents, this should be suspected as a possible cause and the
outlet wiring should be visually inspected.
